' To all whom it may concern:

Be it known that I, GUSTAV Wrennn, a German subject, residing at- Baudette, 1n the county of Beltrami and State of Mmnesota, have invented certaln new and useful Improvements in Door-Locks, of whlch the following is a specification.

This invention relates to an improvement in door locks and more particularly to a lock of this character of the combination or permutation type.

An object of my invention resides 1n providing means by which the bolt securing means can be set to positively secure the bolt against release even by manipulation of the combination parts, may be'shifted toa second extreme position to release the bolt'securing means so that the lock maybe used after the manner of an ordinary spring latch, and is further adjustable to a position intermediate between the two extremes in which the parts will operate after the manner of a mght latch and when the bolt has been thrown, it may be released by proper manipulation of the combinatlon means from the outer side of thedoor.

With the above and other objects in view, which will be in part described and in part understood by the specification, drawings, and claims, my invention consists in certain novel features of construction and combination of parts which will be hereinafter more fully set forth.

In the drawings Figureol is a view in elevation showing the lock structure as the same would appear before application to a door;

Fig. 2 is a transverse vertical sectional view taken substantially through the center of the lock structure;

Fig. 3 is a vertical sectional view taken longitudinally through the casing and substantially on the line 3-3 of Fig. 2; and,

Fig. 4' is a horizontal longitudinal sectional view taken on the line 4-4 of Fig.3.

The lock structure proper is contained within a casing 1 whi h is adapted to be secured on the inner side of a door or within a mortise formed on the inner side, and to be held in place by means of screws or other suita'ble fastenings passed through the openings 2, and this casing 1 has a sleeve 3 formed to extend from that side which is to be placed against the door, the sleeve thus being so arranged that an open ng must Specification of Letters Patent.

- be provided through the door for the reception thereof, and the sleeve thus opens on the outer side of the door. However, it is desirable that Y a cover plate 4 be provided on the inner side of the casing and be removable to permit access to be had to the interior of the casing.

The forward edge of the casin 1 has an opening 5 formed therethrough or the reception of the bolt 6, which bolt at its outer end is beveled diagonally across to take the form of the bolt of a spring latch, and the inner end of the bolt 6 is provided with a slotted opening 7 through which the pin 8 carried by the casing passes to thus hold the bolt to have sliding movement in a fixed path. A leaf spring 9 is caught under a hook 10 provided in the casing and is swung outwardly by a lug 11 so that it bears against the inner end of the bolt 6 and thus resiliently forces the bolt outwardly to such a position that further movement is limited by abutment of the pin 8 against the inner end of the slotted opening 7. A bolt releasing member 12 is suitably mounted in bearing openings rovided in the casing and in the cover p ate 4: so that it is disposed adjacent the bolt 6 and a finger 13 is provided on this bolt receiving member to be loosely fitted in the opening 14 formed in he bolt, so that as the bolt releasing member is turned in a counterclockwise direction, as the parts are illustrated in Fig. 3, the bolt 6 will be withdrawn against the tension of the leaf spring 9 an the beveled end will be retracted into the casing. The bolt releasing member 12 is opening or an opening of other polygonal form, for the rece tion of the knob spindle 15, and the kno s 16 and 17 are provided on the ends of this spindle to be disposed on the outer and the inner sides of the door.

With the parts arranged in the manner as set forth, a structure is provided which to all intents and purposes is substantially identical with the usual form of spring latch, and without additional restraining 1 bolt and with its free end disposed to normally bear against the inner side of the bolt. The bolt shank is notched as shown at 19, and when the spring 18 has unrestrained movement, it moves to engage at its free end behind the shoulder formed by the notching of the same and thus positively locks the bolt against being withdrawn through turning of the knobs 16 or 17. bolt and the lock structure for use upon doors closing either inwardly or outwardly, it is of course essential that the bolt 6 be reversible, to dispose the beveled side of the end thereof properly, and with this purpose in view, I provide a notch 20 on the opposite side of the bolt shank corresponding in its position to the location of the notch 19 and shape the opening 14 to present an equally operative form on both upper and lower sides of the shank. To change the bolt, it is only necessary to remove the cover plate 4, and then raise the bolt 6 from the position in which it is fitted within the opening 5 and over the pin 8, following which thebolt is turned over or reversed and is again fitted in the same position.

It will of course be understood that under normal conditions the spring 18 will be engaged within the notch 19 or 20, and will hold the bolt 6 positively against movement to the released position, and as the combination means, which will be hereinafter more fully described is intended for opening of the lock only from the outer side of the door, it is essential that some means be provided to release the spring 18 from that side of the door on which the casing 1 is mounted, and it is preferable that the means be so constructed that the spring 18 can be positively locked in the bolt securing position and can be left free to act through its own resiliency. 'VVith the above in view, I mount a shaft 21 between the inner side of the easing 1 and the cover plate 4 and provide thereon what might be designated as a tripping member 22, which is made up of the spokes radiating from a hub mounted on the .1/i'shaft 21 and a split rim. The split rim is so shaped at the free end that one end is bent outwardly as shown at 23 whereas the other end is bent inwardly as indicated at 24, and thus when the tripping member 22 is mounted with the main portion of the rim substantially in line with the free end of the spr1ng18,the spring will be received between the ends 23 and 24 and will then be free to act on its own natural resiliency, or when the tripping member is turned in one direct-ion or the other the spring will be shifted under the exertion of a cam action thereagainst by either the ends 23 or 24 in accordance with the direction in which the member .22 is turned. The rim extends through the upper side of the casing 1 and is roughened as shown at 25, a pin or other suitable stop 26 To adapt the to be withdrawn.

. complished as standard being provided to determine and limit the movement of the tripping member to its extreme positions and also to indicate the setting of the spring 18 in the intermediate position or where the spring 18 is free to move into and out of engagement with the sliding bolt. When the tripping member 22. is turned in a clockwise direction, as the parts are illustrated in Fig. 3, the end 24 thereof will engage with the spring 18 on that side which is adjacent the bolt 61 and in consequence the spring 18- will be forced out to be disengaged from the notch in the shank of the bolt in which relation the spring will be positively held until the tripping-member is again shifted. Upon turning of the tripping member in the opposite direction or in a counter clockwise movement, the end 23 engages on the opposite side of the spring 18 and forces the same inwardly to positively lock the spring against movement to a position that it may be disengaged from the notch to the bolt, and of course it will be understood that when the parts are as shown in Fig. 4, the spring 18 can be freely moved from the notch. As has been stated, it is preferable that the extending portion of the tripping member 22 be roughened to give a surface for manual manipulation stop 26 will of course act as a guide in the setting of the parts.

In the foregoing I have described the spring latch mechanism of the lock to thawith the means for securing the bolt 1 the sprung or locked position, and also means for controlling the spring by which the bolt is locked, and it will be. understood that where the lock mechanism is to be usedtasa spring latch and is to be lockedonly from the inside of the door, these parts would doubtless prove suflicien't, however, it is a purpose of my invention to provide combination means by which the s ring 18 can be moved 'to the inoperative position or to a relation in which it is disengaged from the bolt 6 to thus permit the knob 16 to be turned and the bolt As has been stated, the sleeve 3 is disposed from the casing 1 to open at its outer end on the outer side of the dborl'l, that it will terminate flush with the Sitar surface of the door, this being readily acdoors are generally made to be of one and three-eighths or one and three-fourths inches in thickness. Gom bination dials 27, 2'8, and 29, of which three are shown in the resent illustration but of which there might be a greater or lesser number, are each made of successively smaller size, and the dial 27 has a I g side thereof and made of such a. size that it will have a bearing engagement within the sleeve 3 0f the casing, the dials 28'and 29 each being provided Whtll the bearing sleeves .the dial 29 whereas then in setting the permutation disks smaller size and are telescoped or intexrfi turning movement.

A bar 42 is provided with an opening to be received over the shank 41, and a nut 43 is provided to be tightened against the bar to hold the same in predetermined settings upon the shank 41. This bar 42 has a plate or bit 44 carried at one end thereof and made of such will pass into the notches 36 of the several permutation disks when the same have been rought to reglstry, and the plate or bit further has an extension 45 which projects beyond the edges of the permutation disks.
